000646 – “Since when did Hashem start telling Gedolim why he does things? Gedolim can tell us what they reccomend we work on. But since when did Hashem start talking to them, and telling them the reasons things happen?”
The Gedolim are, by definition, the most spiritually developed individuals of their day. Therefore, they have amassed far more knowledge about A) what Hashem wants from us and B) why He wants it than we have. With their superior knowledge of the ratzon Hashem, they can figure out what He wants us to do in any situation.
